MOTOR-SUSPENSION FOR STREET-CARS.

SPECIFICATION forming part of Letters Patent No. 552,347, dated December31, 1895. Application filed August 21, 1895. Serial No. 559,992. (Nomodel.)

To all whom it may concern:

Be it known that I, GEORGE F. CARD, a citizen of the United States ofAmerica, residing at Mansfield, in the county of Richland and State ofOhio, have invented certain new and useful Improvements inlVIotor-Suspensions for Street-Oars, of which the following is aspecification.

The object of my invention is to provide an improved motor-suspension;and the invention consists in the combination and arrangement of partshereinafter described and claimed.

In the drawings, Figure 1 is a plan; Fig. 2, an end elevation on line 22 of Fig. 1, and Fig. 3 a front elevation.

A represents a motor, preferably of iron-clad type, having the workingparts entirely incased, one end of which is supported on the car-axle B.A rectangular frame 0 is provided at one end with socket-lugs c, whichrest upon springs D, carried by the car-truck. The opposite end of therectangular frame 0 is provided with socket lugs 0, supported on springsE, which are supported from the axle, as distinguished from the truck,and are preferably mounted above the axle upon the motor-casing. StrapsF, secured to the ends of the motor-casing, extend along the outside ofthe frame 0 and pivot-bolts G, take through the straps and frame 0 andinto the motorcasing. The straps afford bearings for the outer ends ofthe bolts, and the motor-casing forms bearings for the inner ends, thusgiving a double support and preventing liability of bending, whichfrequently occurs when the bolts have but a single bearing.

A bracket H is secured to the motor and provided with a socket-lug hdirectly over the end of frame 0. A spring I is placed between lug h andthe frame.

Any jar to the motor is transmitted to the rectangular frame and isreceived by springs whatever the direction of movement may be. The motoris pivoted to the rectangular frame and elastically limited in itsmovement relative thereto by springs E and I. Spring I produces alimited compression on springs E, thereby preventing undue oscillationof the motor when passing over rough places in the track and also holdsthe motor against lifting or climbing when the motor is reversed orthere is a sudden increase in the current.

I find that the construction above described affords a compact andelastic suspension which reduces the jarring or hammering to a minimum.

I claim as my invention- 1. The combination,with a motor, of a framehaving one end elastically supported upon the car truck, and the otherend elastically supported from the car axle, and a pivotal connection ofthe motor and frame between the points of support of the frame,substantially as and for the purpose set forth.

2. The combinatiomwith a motor, of a frame having one end elasticallysupported upon the car truck, and the other end elastically supportedfrom the car axle; apivotal connection of the motor and frame betweenthe points of support of the frame; a bracket extending from the motorcasing to a point above the axle, and a spring between the bracket andaxle, substantially as and for the purpose set forth.

3. The combination withamotor of aframe, 0, supported at one end uponsprings, D, and at the other end upon springs, E, a bracket, H a spring,I, between the bracket and frame the straps, F; and the pivot bolts, Gr,substantially as and for the purpose set forth.
